[0040] (first embodiment, refer to Figure 1 to Figure 4 )

[0041] like figure 1 As shown, in the paste coating apparatus of the first embodiment, the paste containers 10 and the paste coaters are provided on the left and right sides of the conveyance path of the sheet parts 2 held on the conveyor belt 1 at predetermined intervals. Apply wheel 11 and paste wheel 12. The sheet parts 2 are conveyed in a state of being in contact with the outer peripheral surface of the paste wheel 12 .

[0042] That is, the paste application wheel 11 and the paste wheel 12 are driven to rotate at the same peripheral speed in the directions of the arrows while the outer peripheral surfaces are in close contact with each other. like image 3 As shown, four grooves 12a to which the paste is attached are radially formed on the outer peripheral surface of the paste wheel 12 .

[0043] In this first embodiment, as figure 2 As shown in (A), a pair of scraping blades 16 are provided on a portio...

no. 2 example

[0050] (Second embodiment, refer to Figure 5 to Figure 7 )

[0051] like Figure 5 and Image 6 As shown, the paste application apparatus of the second embodiment is basically the same in structure as the first embodiment described above. The difference is that the restricting blade 13 provided on the paste wheel 12 is omitted, and in addition to the scraping blade 16 on the paste coating wheel 11, a pair of blades attached to the outer peripheral surface of the wheel 11 is also provided. The restricting blade 17 restricts the film thickness of the paste.

[0052] The restricting blade 17 is disposed on the portion where the lower portion of the paste application wheel 11 is lifted from the paste P filling the container 10 , and is positioned above the pair of scraping blades 16 . The front end of the restricting scraper 17 does not come into contact with the outer peripheral surface of the wheel 11, and the amount of the paste adhering to the outer peripheral surface of ...

[0054] (The third embodiment, refer to Figure 8 and Figure 9 )

[0055] For the coating device of the third embodiment, such as Figure 8 and Figure 9 As shown, a scraper 18 having a function of integrating the scraper scraper 16 and the restriction scraper 17 shown in the second embodiment is provided on the paste application wheel 11 .

[0056] The scraper 18 has a U-shape with a recess 18 a whose bottom is opposite to the outer peripheral surface of the paste coating wheel 11 , and both sides of the recess 18 a are in contact with both sides of the wheel 11 . As a result, the bottom edge of the recessed portion 18a, like the restricting blade 17 shown in the above-described second embodiment, restricts the amount of the paste adhering to the outer peripheral surface of the wheel 11 so as to be sufficient to accommodate the paste In the groove 12a of the wheel 12, it can also be transferred to the outer peripheral surface of the paste wheel 12, so that the paste also ...

Abstract

The invention provides an apparatus for applying paste, by which paste can be prevented from being stuck / solidified on the side face of a peripheral part of a paste applying wheel and can be applied stably to a chip type component and to provide a method for manufacturing the chip type electronic component. The apparatus for applying paste, which is used for applying the paste packed in a groove arranged on the outer peripheral surface of a paste wheel 12 to the end face of the chip type component 2, is provided with: scraping blades 16 which are arranged respectively on both sides of the paste applying wheel 11 for supplying paste to the paste wheel 12 from a paste vessel 10 and are used for scraping the paste stuck to both side faces of the peripheral part of the paste applying wheel 11; and a regulation blade 13 arranged to be brought into contact with the outer peripheral surface of the paste wheel 12.

Description

technical field [0001] The present invention relates to a paste coating device, in particular to a paste coating device for coating electrode paste on the surface of sheet-type electronic devices such as capacitors, and a method for manufacturing a sheet-type electronic device using the device. Background technique [0002] Conventionally, techniques disclosed in Patent Documents 1 and 2 have been known as such a paste coating apparatus. like Figure 11 As shown, the schematic configuration of the paste application device disclosed in Patent Document 1 is that paste containers 10, paste Sludge applicator wheel 11 and paste wheel 12. [0003] The paste application wheel 11 and the paste wheel 12 are driven to rotate at a uniform peripheral speed in the directions of the arrows, respectively. A groove (not shown) to which the paste adheres is formed on the outer peripheral surface of the paste wheel 12 . [0004] In a state in which the wheels 11 and 12 are driven to rotate...
